[Contrib: Evaluation System] provider not being called

[Richard C. Moyer II]

Chuck & Aaron,

            First, I would pull the latest AdminTestEGProviderProducer.java from trunk.  I've fixed this bug a while ago. This should let you know if your provider is working.

            If you're importing all the evaluation data (i.e: items, scales, templates, evaluations), then you also must populate the tables created by the evaluation. These tables provides the link between the evaluation and the groups and students.  These are the eval_assign tables and I'm sure there are other set up requirements..  Since we don't run evaluations in this manner, I can't give much more guidance.

            I would create an evaluation within sakai and make sure that  your groups are appearing when asking.

            You mentioned that you're using the course-management for courses not in sakai, again, sorry but we don't use that.  Also, unless the course management data is called from your group provider, I don't think it will be display in the AdminTestEGProvider.

            Here's a summary of how UMD has implemented Eval Group Provider.

Evaluation is the ONLY tool we use within sakai.  Evaluation and person data are retrieved via providers.
I create 2 tables which store data for the Eval Group Provider

Eval_umd_title contains groupId, title, student and instructor counts and some UMD specific data
Eval_umd_stu contains groupId, UMD directory ID, permission (TAKE, BE, TA) and other UMD specific data

These tables are populated via an extract process from UMD Student Information System. All methods in the EvalGroupProvider access these 2 tables.

The only method I added was to translate UMD directory ID to the sakai id via the sakai-user-id-map table. When an evaluation is created, any person without a sakai id has one created and mapped to their EID.

            Be sure and read Jim's note and Aaron's response, when an evaluation is created the data is transferred from  eval_umd_title to eval_assign_groups and from eval_umd_stu to eval_assign_users.


Sorry, I couldn't be more helpful, but I would update the test provider and look into the relationship between the eval group provider and course-management code.
Rick

Hi Richard,

I work with Chuck at Rutgers.  I will try to answer your questions and Chuck can
correct me if he feels the need.

Charles,

       Here at Maryland we also use the eval group provider, but unfortunately, I cannot reproduce your error. Currently I'm in the middle of testing evaluation trunk, revision 70243, against our config and providers with the hope of migrating to sakai 2.7.

       To help trouble shoot your situation, we'll need a little more details.

1. 'We're not seeing people in our evaluations' - are you signing on as a student and there are no evaluations or are signing on as an instructor or admin?

We tried both.  The students see no evaluations and the admins see 0 students in the evaluations.
2. 'Our evaluations come entirely from the Rutgers provider.' - are you building your evaluations outside of the sakai evaluation tool and importing in or are you building the evaluation using this tool and your groups, students, instructors, and TA come from your provider?

We import the evaluation data directly into the database.

3. 'old code' do you have a date or revision number?
I believe it was the 1.2 stable release.

4. 'new code' do you have a date or revision number?

1.3 RC 2.

5. what are the results from the Test EvalGroupProvider from the Administrate screen? As an admin, student & groupId.
Are you getting  back Rutger's IDs or sakai IDs?

"Unexpected error" with the following (abbreviated) traceback in catalina.out

6. are you using a UserDirectoryProvider?

Yes.



It doesn't look like it.  Should we be?
The Rutgers interface implements the following signature

public class RutgersEvalGroupsProvider implements org.sakaiproject.evaluation.providers.EvalGroupsProvider {...}


Our provider isn't Rutgers-specific. It simply connects to course management. We evaluate courses that don't have Sakai sites, so we need to go directly to CMS. We have no way to know who the instructors are, so we only return students, i.e. the provider code all returns nothing unless the permission is TAKE.


The summaryProducer, and supporting code has gone through several enhancements and re-writes over the years. It's possible that depending on how old your code is that your caught in a void that has since been fixed.

Please let us know this info and perhaps we can dig a little deeper into the code.

Thanks for your attention.  -- Aaron Watters (aaron at rutgers.edu<mailto:aaron at rutgers.edu>)
